Dear all:
For simpleFoam solver, what is the exzct meaning of P in case/0/P file ?
It is refference value or the actual value ?
for initial field and outlet condition , we should set 0 or 101325/rho ?
Because I saw many imcompressible case set it to 0, but I set 101325/rho .
Thank you very much.

There is no meaning for the value of p in incompressible flow. Only the gradient term of p is appeared in Navier-Stokes eq.
You can start both from p=0 or p=101324/rho, then simulated result may be translate by constant value.
